When year 3 launches you should be able to pick servers for year 1 and year 2, keeping the characters you had at the end of that year. For example for year 1 servers, you would keep your characters you had at the end of House Of Wolves with all the gear you left it with, and all of the patches before TTK were still there. You would be able to switch back to the year you want by going to the Destiny start menu. All of the gear would still be saved on that year you were on before and not carry over to another year. I think this would be a good idea because alot of year 1 players could go back and experience the best year in Destiny, and all of the new players who came in TTK could try the old Destiny. I doubt Bungie will look at this but if they do, I hope they think about this.
